The teaching of design principles for removable partial dentures has largely been relegated to one-on-one or small group situations primarily because of the limited size of the diagnostic casts and instruments used. This problem can be circumstantially overcome by pro.jecting 3.5mm slide views of diagnostic casts on either a paper flip chart or a white porcelain chalkboard Diagnostic casts should be surveyed and tripoded before

photographing. The following views should be photographed for slide pro,jection: (1) occlusal views of unarticulated casts and (2) right and left lateral, anterior, and lingual views of articulated casts. Drawings made with colored water-based markers can be superimposed on the projected images enabling a large number of individuals to observe and participate in the design procedures (Fig. 1). Line drawings made to overlay the projected images can be used to indicate proposed mouth preparations as well as the removable partial denture design. Changes in design or alternatives can be made by simply erasing the porcelain chalkboard or turning to a new page on the flip chart.
